摘要： Systems and methods are provided for maximizing call throughput in a server network by optimizing the balance of stateful to stateless handling or transactions at each server within the network. The identification of transaction messages to be handled statelessly or statefully is made at each proxy server within the network in order to maximize the total throughput at that proxy server within prescribed processor utilization limits. In general, each transaction is handled statefully by at least one server within the network. Reports on the stateful handling of messages and the resource consumption at various proxies are communicated throughout the network to be used in identifying the ratio of messages to be forwarded statefully to messages to be forwarded statelessly at any given proxy.

摘要： Systems, methods, apparatuses and program products configured to provide a topology-service tool are described. A presence-federation solution asset is leveraged to address topology-federation problems. A network topology tool takes as input network endpoints, for example caller and callee telephone numbers, determines a network service flow used to connect the network endpoints, and develops a network topology view of the service flow along with associated network device related information.

摘要： Systems and associated methods for providing scalable presence subscriptions in federated presence environments are described. Embodiments provide for intelligent addition of subscriptions to a presence system. Embodiments identify if a virtualized presentity (corresponding to a new query) can be composed from existing virtualized presentities, and if so, corresponding query processing cells (QPCs) (servicing existing queries) are reused to retrieve the presence information (partially or fully) for the new incoming query. Embodiments organize the existing QPCs into a hierarchy such that a QPC/virtual presentity at a higher layer fetches presence information of all or some presentities from QPCs/virtual presentities at lower layer(s) to service the new query.

摘要： The present invention is directed to a session initiation protocol (SIP) infrastructure containing various user devices and the use of this infrastructure to conduct media exchange sessions among the various user devices. Included in the user devices are wearable devices, for example pendants and wrist watches, that provide readily available and accessible devices for use in controlling the media exchange sessions. SIP permits the separation of the control aspects of a session from the actual media exchange aspects to facilitate the use of wearable devices having limited processing resources as control devices. The actual media exchange is directed to user devices suitable for sending, receiving and displaying the exchanged media.

摘要： A method for operating a server having a maximum capacity for servicing requests comprises the following steps: receiving a plurality of requests; classifying each request according to a value; determining a priority for handling the request according to the value, such that requests with higher values are assigned higher priorities; placing each request in one of multiple queues according to its priority value; and dropping the requests with the lowest priority when the plurality of requests are received at a rate that exceeds the maximum capacity. The server operates according to a session initiation protocol.Classifying each request comprises running a classification algorithm. The classification algorithm comprising steps of: receiving a rule set, each rule comprising headers and conditions; creating a condition table by taking a union of all conditions in the rules; creating a header table by extracting a common set of headers from the condition table; extracting the relevant headers from the header table; determining a matching rule; creating a bit vector table; selecting the matching rule according to data in the bit vector table; and applying the rule to place the message in the appropriate queue.

摘要： Systems and methods are provided for monitoring session initiation communications without modifying the operational code of the session initiation protocol proxy servers through which the messages that constitute a given communication are routed. The inbound and outbound versions of session initiation protocol messages are identified at a plurality of proxy servers. The inbound and outbound message versions are correlated at each proxy server using user-defined correlation rules that test conditions of the message headers. The correlated inbound and outbound message versions are then examined for transformations, and these transformations are used to determine the actions taken by the appropriate proxy server on that message. These actions are used to check the proper operation of both the proxy server and the session initiation protocol communication.
